WRL Globe Chief 90 CW transmitter, with WRL
755-A VFO

This was my first transmitter, which, along with the HQ-140-X,
comprised my first station as a NOVICE WD8PCE in 1977. Sitting on
top of the VFO is an accesory screen modulator for AM phone.

The WRL-90 tube lineup is straightforward, being a 6AG7
oscillator/buffer , a 5U4G rectifier, and a pair of 807s in
parallel as the final amplifier. It has a maximum DC input power
of about 90 watts. The 755-A VFO consists of a 6AU6 oscillator,
6CB6 buffer, and an 0A2 regulator. The VFO and the transmitter
cover the traditional ham bands from 160 m to 10 m. The screen
modulator has a 12AX7 speech amplifier and a 12AU7A modulator.
